In the contract data, a follow-up action has been defined that
specifies a follow-up quotation or a follow-up contract. In this case,
you should define a completion rule for the contract-relevant item(s).
There is at least one contract-relevant item for which no completion
rule has been defined.

How to fix this error?

Contact your system administrator.
In Customizing, in Sales/distribution, you should make the following
settings:
In chapter 'Define item categories', you should enter a completion rule
for contract-relevant items.
In chapter 'Maintain copying control for sales document types', you
should set the field "Quantity/Value' to '+' at item level.
As a result, the contract-relevant items will be completed when they
are transferred into a subsequent document.
